Hi all,
I am new to gnuradio and stuck with the usrp2 connection for several days...
I looked up tens of search results but no solution yet. Therefore I post my
problem and hope someone could give me a hand:
I am running gnu radio 3.2.2 on ubuntu9.10, and I think gnuradio works fine
because dial_tone.py and grc all could be launched correctly. However, when
I plug in USRP2, problems happen:
if I typed in "sudo find_usrps" it says: No USRP2 found.
if I typed "sudo find_usrps -e eth0" it also says No USRP2 found. (eth0 is
what I get when typing in ifconfig)
if I typed in "sudo usrp2_fft.py" t says:
Traceback (most recent call last):
File "/usr/local/bin/usrp2_fft.py", line 273, in <module>

in source_32fc
return _usrp2.source_32fc(*args, **kwargs)
RuntimeError: No USRPs found on interface eth0
What exactly the problem is?
TO note:
1. python is fine. I ran following process and it did not say error:
Python 2.6.4 (r264:75706, Dec 7 2009, 18:45:15)
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from gnuradio import gr
>>> from gnuradio import usrp
>>> from gnuradio import audio
>>> from gnuradio import usrp2
>>> exit()
2. could it be the firmware in usrp2? I saw some threads discussing firmware
in SD card. But it seems to run process like usrp2_fft.py dose not need any
firmware.
3. my usrp2 runs fine. I checked it with another computer which could launch
usrp_fft.py correctly. Also, when I power on usrp2, all 6 lights flah and
then D and F remain on.
4. my ethernet card should be fine. it is gigabit. here is what it says when
I type in "sudo ethtool eth0":
Settings for eth0:

I am really confused and find no solution on my own. Any suggestion would be
greatly appreciated. I will wait online and provide any additional
information if you need.
